A mixed radiopaque - Radiolucent lesion in the anterior mandible associated with multiple impacted teeth: A radiodiagnostic challenge?

Abstract

Desmoplastic ameloblastoma (DA) exhibits important differences in gender, anatomic distribution, radiographic findings, and histologic appearance compared to other types of ameloblastoma. Radiologically, DA is seen either as ill-defined mass containing osteolytic and sclerotic areas or as multifocal radiodense flecks within radiolucent background resembling a honeycomb. The radiographic differential diagnosis includes fibro-osseous lesions such as cemento-ossifying fibroma, fibrous dysplasia, calcifying odontogenic cyst, and chronic sclerosing osteomyelitis. Thus, DA should primarily be included in the differential diagnosis of a mixed radiopaque-radiolucent lesion with diffuse borders in the anterior premolar region of the jaws. This report adds to the literature of mixed radiolucent-radiopaque lesions which may not always be histopathologically diagnosed as a fibro-osseous lesion but could turn out to be a DA. This report also benefits the dental community by cautioning them to be aware of DA that can be associated with multiple unerupted teeth which is quite a rare finding.
